On clicking submit after editing an empty user page (link appears as http://www.wikidata.org/w/index.php?title=User:Jeblad&action=submit) I get an "internal error" saying [39c065a3] 2012-10-26 23:53:41: Fatal exception of type MWException.
On the page the text seems pretty safe, only a few iw-links, but replacing the text with "foo" turned up another message, now the message "Missing wiki" and I'm redirected at Meta.
Version: unspecified
Severity: normal
